Threatened Species

I did some research for an upcoming side project to see how New Zealand compares to other countries in terms of threatened species. When I compared NZ to the rest of the world using the IUCN Red List (2013) we look ok, but things look much worse when we factor in our relatively small land mass. However poor countries like Ecuador are doing much worse than us, probably because the human/environment conflict is so high. However if we just look at OECD counties the same size as New Zealand or larger New Zealand has the most threatened species of birds per KM2

Here is the ranking:

  1. New Zealand
  2. Japan
  3. Chile
  4. Turkmenistan
  5. Italy
  6. Mexico
  7. Poland
  8. Spain
  9. Turkey
  10. Germany
  11. Finland
  12. United Kingdom
  13. France
  14. Norway
  15. Sweden
  16. United States
  17. Australia
  18. Canada

And the raw data
